All kinds of sensors, such as temperature, electric current,  voltage, humidity, velocity, pressure, etc., can be connected to A/D channel. A/D Meter widget of N-Button Pro/ Lite will read the value of A/D channel and show the value on the screen. The raw value of A/D channel is 0-255. The meter can map the value to different range, like 0-5, which is voltage on A/D channel or other value you want. The widgets can update the value at specific interval automatically as well as refreshed manually.
